GEORGE E. STEENROD, OF FREEPORT, ILLINOIS. I

REGULATOR FOR WINDMILLS.

SPECIFICATION forming part of Letters Patent No. 728,513, dated May 19, 1903.

' Application filed February 4, 1903; Serial No. 141,938. tNo modell) T0 all whom tmay concern.-

Beit known that I, GEORGE E. STEENROD, a citizen of the United States of America, residing at Freeport, in the county of Stephenson and State of Illinois, have invented a certain new and useful Improvement in Regulators for Windmills, of which the following is a specification.

This invention relates, specifically, to an automatic regulator for throwing windmills into and out of gear, according as there beinsuf- Iicient or sufficient Water in the tank thereof; and it consists of certain new and useful features of construction and combinations ofparts'especially devised to that end, all as hereinafter fully described, and specifically pointed out in the claims.

Referring tothe accompanying drawings which form a part of this specification, Figure l is an isometrical view of a windmill-regula-- tor embodying myinvention attached to one of the posts ofa windmill-tower. Fig. 2 is a front elevation of the regulator with parts broken away. Fig. 3 is a top plan View of the parts shown in Fig. 2. Fig. 4 is a section at' the dotted line 4 4 in Fig. 2 of parts there shown. Fig. 5 is a section at the dotted line 5 in Fig. 4 of parts there shown. Fig. 6 is a view showing modified means for connecting the fioat with the windmill-regulator when the tank is at a distance from the tower and should be entirely disregarded, except when reference-is being made hereinafter to such modified connecting means.

Like letters of reference indicate corre-m sponding parts throughout the several views.

A is the base-platev ofthe machine, which has a vertical slideway A A2 therein and is provided with lugs A3 A4 A5 A6 A7 A8, the uses whereof will be designated. hereinafter.

B isa rack having teeth B' extending along one edge thereof and slidably mounted in the slideway A' A2 in the base-plate A.V

C is a wire connecting the rack B'by its upper end with and suspending it from the pull-out mechanism of the windmill mechanism common and very Well known in Windmill construction.

D is a pump-rod connected above with the crank-pin of a windmill of any ordinary construction and below with a pump D.

E is a pawl-actuating lever horizontally mounted between its ends on a pivot-bearing E', inserted through the lug A2 and plate A, and is pivotally connected by one end E2 with the pump-rod D.

F is a pawl jointed by meansof the pivot zontal stud-pivot H on the plate A, provided with a horizontal lug Ha and having its vertical furcations H2"H' very loosely bestriding thehorizontal furcations of the lever G.

I is a detent mounted on a horizontal studpivot-I on the plate A, normally held into engagement'with the teeth BL of the rack B by means of the lever-Weight I2 and adapted to be thrown out of engagement with such rackB by the lug Ha onthelever H.

.I is a horizontal tilting-beam rigidly secured at a point preferably about midway between its endsto the lower end portion of the furcated lever H.

K is a tank partly Iilled with water K.

L is a Iioat suspendedY from the end J of the beam J by means of a wire L.

M is a weight slidablyadjustable alongthe free end of the beam J'and serving to balance the iioat L in the water'KL N-N'v N2 are'bolts inserted through holes N3 N4 N5 in lugs A4 A5 A6 on the base-plate A-and through corresponding holes in the clip O to rigidly secure the regulator to one of the angle-steel posts P of the tower P.

Whenever the ,tank K is at a distance from Vthe tower P', the upper endi of the wire L',

Fig. 6, is connected with` thehorizontal arm of a bell-crank L3, mounted on a post`L2,and.

a wire L4 is extended from the vertical arm of such bell-crank L3 through and fastened in a hole H4 in the furcation H2.

When the tower is wide or the stroke of the mill is too short, the pivot-bearing E' should be shifted from the position shown in Figs. 2 and 3 to the holes Q Q Q2 in the lug A7, 1ever E, and base-plate A inv order to insure the proper working of the regulator.

IOO

The drawings show the water-tank filled, the regulator at rest, and the mill held out of gear by the wire G. If now any considerable amount of water be withdrawn from the tank by the drinking of animals or otherwise, the float L will descend and, acting through the beam J, tilt the lever H in the direction indicated bythe arrow in Fig. 2 until it strikes and rests against the lug AS. The movement of the lever H just described causes the lug H thereon to strike and disengage the detent I from the rack B and the fureation H2 thereof to strike the furcation G2 of the lever G, which in turn strikes and also disengages the pawl F from such rack B,

' thereby releasing the latter and through it the wind-wheel of the mill, which will then go into operation and pump water until the iioat L rises suticiently to be overbalaneed by the weight M, which will thereupon tilt the beam .l in the opposite direction and, acting through the furcated levers G H, throw the pawl F into engagement with the rack B and also permit the weight l2 to throw its detent I into engagement therewith. The mill will then continue to operate the pump and through its rod D oscillate the lever E until the pawl F thereon has driven the rack B downward in its slideways A .A2 in the baseplate A until the mill is again pulled out of gear by the wire C.

The joint operation of the weighted furcated lever G and the furcated lever H is to cause the pawl F and detent I to swiftly and surely engage with and disengage from the rack B at the proper times.

What l claim as new, and desire to secure by Letters Patent, is-

l. In a regulator for windmills, in combination, a base-plate having a rack-slideway therein, a rack slidable in such slideway, a pawl-actuating lever pivot-ally mounted on the base-plate, a pawl mounted on a pivot on the pawl-actuating lever and adapted to be thrown into and out of engagement with the rack, a furcated lever-mounted on the same pivot as the pawl-actuating lever-carrying a weight, at its upper end, and having its horizontal furcations loosely bestriding the pawl, a detent, mounted on a pivot, on the baseplate, and normally held into engagement,

with the rack, by means of a lever-weight, a furcated lever-mounted on a pivot on the base-plate-provided with a lug, adapted to throw the detent out of engagement with the rack, and having its vertical fnrcations very loosely bestriding the horizontal fureations ofthe Weighted furcated lever, and means for tilting the lever, having vert-ical fureations, back and forth, substantially as and for the purpose specified.

2. In a regulator for windmills, in combination, a base-plate having a rackslideway therein, a rack slidable in such slideway', a pawl-actuating lever pivotally mounted on the base-plate, a pawl mounted on a pivot on the pawl-actuating lever and adapted to be thrown into and out of engagement with the rack, a fu rcated lever-mounted on the same pivot as the pawl-actuatiug lever-carrying a weight, at its upper end, and having its horizontal fureations loosely bestriding the pawl, a detent, mounted on a pivot, on the baseplate, and normally held into engagement with the rack, by means of a lever-weight, a furcated lever-mounted on a pivot on the base-plate-provided with a lug, adapted to throw the detent out oi' engagement with the rack, and having its vertical furcations very loosely bestriding the horizontal furcations of the weighted furcated lever, and a tiltingbeam secured, between its ends, to the lever having vertical furcations, substantially as and for the purpose specied.

3. In combination, a Windmill-tower post of angle form'in cross-section, a windmillregulator base-plate, provided with connecting-lugs having bolt-holes extending therethrough, a clip O having bolt-holes therein, and bolts N N N2, inserted through and secured in the holes in the lugs in the baseplate and clip, to secure such base-plate to a tower-post of the form indicated, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

GEORGE E. STEENROD.
